Figure Lengend Snippet: Ileum and colon tissues were collected from mouse recipients at 21 days post gavage and analyzed for frequencies of CD69+ and CD103+ T cells. (A) Gating strategy for CD69+ T cells. Representative plots from ileum tissues are shown. (B-C) Frequencies of (B) CD69+ CD8+ T cells, (C) CD103+ CD8+ T cells, and (D) CD103+ CD4+ T cells in the ileum. (E) Frequencies of CD69+ CD4+ T cells in the colon. Each data point represents a single mouse gavaged with an individual donor’s feces, and a representative mouse was used for stools tested in replicate mice. Lines represent medians. Statistical analyses were performed using t-tests to compare groups if data from both groups had normal distributions and Mann-Whitney tests to compare groups if data from at least one group had a non-parametric distribution. ** = p<0.01, * = p<0.05.

Article Snippet: 0.5–1 x 10 6 ileum and colon cells from each mouse were stained in FACS buffer for 30 min at 4° C with the following antibodies: CD3-PerCP-Cy5.5 (17A2, Biolegend), CD4-FITC (RM4-4, eBioscience), CD8-BV510 (53–6.7, Biolegend), CD69-PE-Cy7 (h1.2F3, eBioscience), CD103-PE-Dazzle-594 (2E7, Biolegend).

Figure Lengend Snippet: mLN from mouse recipients were collected and analyzed for effector memory CD4+ T cell frequency (CD44+ CD62L-) using flow cytometry. (A) Comparison of frequencies of CD44+ CD62- CD4+ T cells in the mLN across recipient groups. (B) Spearman correlations of effector memory CD4+ T cell (T em ) frequencies in the mLN with frequencies of CD69+ CD4+ T cells in the colon. Each data point represents a single mouse gavaged with an individual donor’s feces, and a representative mouse was used for stools tested in replicate mice. Lines represent medians. Statistical analyses were performed using t-tests to compare groups if data from both groups had normal distributions and Mann-Whitney tests to compare groups if data from at least one group had a non-parametric distribution. * = p<0.05.
